SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 329,333, dated October 27, 1885.

Application filed October 10, 1884. Serial No; 145,175.

To all whom, it may concern.-

Be it known that I, PATRICK K. OLALLY, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Blind-Operators, of which the following is a specification.

This invention has for its object to provide improved means for operating window blinds and shutters from the inside of a building; and it consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of a portion of a blind and casing provided with my improvement, the blind being closed. Fig. 2 represents a sectional view of the casing and an edge view of the blind, the latter being in the position shown in Fig. 1. Fig. 3 represents a sectional View of the casing like that shown in Fig. 2, the blind being half opened or at right angles to the side of the building. Fig. 4 represents a section on line y y, Fig. 2. Fig. 5 represents a section on line 00 at, Fig. 2.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the windowcasing, and b one of the blinds or shutters.

0 represents the operating-rod,which passes through a socket in the casing, and has an operatinghandle, c, at the inside of the building, and is bent substantially at right angles at its outer end outside of the building to form an arm, 0 The rod 0 is adapted both to move endwise and to rotate in the socket in the caslng.

(1 represents a slotted plate or bar,provided at its end with trunnions e e, which are set in socketed ears or lugs f g, affixed to the outer side of the blind, said ears or lugs being arranged to support the slotted plate at in a diagonal position, as shown in Figs. 1 and 3. The arm 0 passes through the slot in the plate d, as shown, the slot being of such length as to permit the arm to stand horizontally, as shown in Fig. 1, or about vertically, as shown in Fig. 3, the arm being changed from one p0- siti on to the other by rotating the rod 0. \lhen the blind is entirely closed, as shown in Fig. 1, an endwise outward movement of the rod 0 will cause the arm 0 to press outwardly against (N0 model.)

the slotted plate, and thus force the blind out wardly until it stands at right angles with the side of the building, as shown in Fig. 3; then a partial rotation of the rod will cause the arm 0 to swing. and thus move the blind beyond said position, and, finally, an inward endwise movement will cause the arm 0" to pull the blind back to the side of the building, the blind then being entirely opened. The described movements may be made in rapid succession, the rod being rotated while it is being moved endwise, so that the blind can be rapidly opened. The same operation is required to close the blind. It will be seen that the rotation of the rod enables the arm 0 to move the blind beyond the dead-pointt'. 6., a position at right angles with the side ofthe buildingthus preventing the blind from sticking at said point,as it would be liable to do if the operating-rod were capable only oftheendwise movement. The inner end of the rod is provided with screw-threads or corrugations. A plate, 6, recessed and serrated at its lower end,so as to engage With the corrugations of the rod, is suspended upon an eccentric, j, on a stud, 7c, the inner end of which is swiveled in a plate, Z, secured to the casing or wall. The rotation of the stud k causes its eccentric to raise or depress the plate t'. \V hen the plate is depressed, its notched end engages with the rod 0 and locks the same so that it cannot be moved endwise. Provision is thus made for holding the blind when it is entirely opened, or when it stands out at various angles with the wall, the presence of the arm 0 in the slotted plate (1 enabling the locked rod to hold the blind with considerable firmness. I have shown the lug 9 provided with a series of orifices, 0 0, either one of which is adapted to receive a stud, p, on the outer end of the arm 0. The engagement of said stud with either of said orifices also looks the blind, the blind being held in different positions by engaging different orifices with the stud, as shown in Fig. 4.. It will be seen that the slotted plate d turns on its trunnions or pivots as the rod 0 rotates, and thus accommodates itselfto the swinging movement of the arm 0 I am aware that a rod formed to extend through a window-casing and bent at its outer end to form an arm,combined with an attachment on the blind to receive said arm, is not new, and I do not claim the same, broadly.

I claim-- 1. The rod c,eXtending through the window casing, and adapted both to rotate and to move lengthwise,and provided with the arm c,combined With the diagonally-arranged slotted plate d, pivoted to ears 1 on the outer side of the blind, and adapted to turn on its pivots to accommodate itself to the rotary movements of the rod, as set forth.

2. The combination of the rod 0, extending through the Window-casing, and provided at its outer end with an arm, 0 engaged with an attachment on the blind, and at its inner end with screw threads or corrugations; and a plate, i, notched or serrated to engage Wit-h the teeth or corrugations of the rod, and the stud k, having the eccentric 3', whereby said plate is supported and operated, as set forth.

3. The combination of the ear 9 011 the blind, having orifices 0 0, and the operating-rod 0, having anarm, 0 and a stud, 10,0n said arm, formed to enter either of said orifices, and means, substantially as described, for locking said rod, asset forth.

In testimony whereof I have signed my name to this specification,in the presence of two subscribing Witnesses, this 2d day of October, 1884.
